3.2.1 Comprehensive Energy-Saving Measures for Buildings
Contribute to the Achievement of National Goals in
Energy Conservation and Emissions Reduction
In line with increasing urbanization, the constant rise in living standards and stronger
demand for energy consumption from buildings, significant effects were determined
for the building of energy conservation efforts in the 11th Five-Year Plan period, which
turned the tables by slowing down the speed of housing area expansion and increased
energy consumption from buildings. Specifically, an obvious regression was noted in
the average growth of total housing area, or average gross floor area per capita
expansion, during the 11th Five-Year Plan period, compared with that of the Tenth
Five-Year Plan period (Figs.
3.3
and
3.4
). Accordingly, national energy consumption
for buildings and overall energy consumption for all kinds of buildings increased during
the Tenth Five-Year Plan period, sometimes higher than 10 % per year and as high as
15 % in terms of energy consumption for public buildings. During the 11th Five-Year
Plan, however, the speed for national and all kinds of building energy consumption
began to reduce to averaged 7 %, nearly 3 % lower than that of 10th FYP (Fig.
3.5
).
With the sustainable development of socio-economic development and the
constant improvement of the people's living standard, the building area and relating
energy use will inevitably grow naturally. While the expansion of housing areas and
average gross floor area per capita, the growth of overall building energy consump-
tion and that of average floor area per capita, were on a slow track, thereby
revealing the effects of energy conservation efforts, benefiting from energy-saving
measures taken in that period.
